Why Bing Rewards has less features in several nations as compared to the US?

There are a lot of features in Bing Rewards which are missing in India, such as sweepstakes, roblox gift cards, quests and punch cards, daily sets, quizzes, etc. The amount of points distributed per search is also less (3 per search) when compared to what the users in the US and a few other nations get (5 per search). This is not only happening in India but also in several other nations. Can someone explain why? It seems that we might never actually recieve these features as Microsoft is biased even though the majority of their users are from other parts of the world.
